RUNNING AND KNEE PAIN: CAUSES, PREVENTION, AND 3 MUST-DO EXERCISES

The Sun Run is around the corner.

Training volume goes up. Hills get added. Motivation is high.

And then your knee starts to ache.

Not sharp at first. Just tight. Maybe sore after a run. Maybe worse, running downhill. Then one day you realize… it’s not going away.

Let’s talk about why knee pain builds up when running — and what you can do about it.

Why Knee Pain Happens When You Run

Most knee pain isn’t random.

It’s load + mechanics + capacity.

Your knee sits between your hip and ankle. If either one isn’t doing its job well, the knee absorbs extra stress.

Over thousands of strides, that adds up.

Common Causes of Knee Pain from Running

1. Sudden Increase in Mileage

Going from minimal running to 5–10km several times per week. Adding hills too quickly. Increasing distance without gradual progression. Your tissues need time to adapt.

2. Weak Glutes and Core

When hip muscles don’t stabilize your pelvis, your knee collapses inward with each step. This often shows up as pain on the outside of the knee.

3. Running Downhill

Downhill running increases load through the front of the knee. If your quads and hips aren’t prepared, irritation builds quickly.

4. Ankle Stiffness

Limited ankle mobility forces the knee to compensate. The joint bends more and absorbs more force than it should.

5. Posture and Desk Work

Long hours sitting tighten hip flexors and weaken glutes. Add running on top of that, and muscle imbalance becomes obvious.

6. Training Errors

Abrupt increases in distance, speed work added too soon, or running every day without recovery.

7. Running Shoes

Shoes matter — but not because they’re trendy. The right shoe depends on your gait, mechanics, and structure.

We collaborate with trusted running retailers in Vancouver who properly assess your running pattern. Together, we help match the right shoe to your body — not just the latest model on the wall.

Why Knee Pain Creeps Up on You

Knee pain rarely explodes overnight.

It builds quietly.

Your body adapts until it can’t anymore.

A little tightness becomes a mild ache.

A mild ache becomes pain halfway through your run.

Then it starts affecting daily life.

By the time most people seek knee pain treatment, the irritation has been brewing for weeks.

Your body was giving you signals. They were just easy to ignore.

What Happens If You Leave Knee Pain Untreated?

Compensation.

When the knee hurts, your body shifts load elsewhere.

That can lead to:

  • Hip pain
  • Low back pain
  • Ankle stiffness
  • Achilles irritation
  • Foot discomfort

Now it’s no longer just a knee issue.

Persistent irritation can turn into tendon overload, chronic inflammation, and longer recovery timelines. The longer it lingers, the harder it is to calm down.

You do not have to “just live with it.”

Sometimes It’s Not Even the Knee

Knee pain can stem from:

  • Weak core stability
  • Hip muscle imbalance
  • Poor running mechanics
  • Flat feet or high arches
  • Leg length differences
  • Stiff upper back affecting posture
  • Repetitive strain from work or sport

The knee is often the victim, not the culprit.

This is why a proper assessment matters.

3 Exercises to Do Before Your Run

Simple. Effective. No complicated equipment.

World’s Greatest Stretch - Mobilize

  • Start with both hands on the floor in a lunge position. Lower the hips, stay tall in the chest
  • On the side with the knee up, drop the elbow down towards the floor - breathe
  • Turn towards the knee that is up and reach up - breathe
  • Keep the back knee straight
  • A stretch should be felt at the front of the hip with the leg that is back and rotation in your mid spine when reaching up
  • Flow through these movements slowly to mobilize

3 X 10 reps

Pelvic tuck - Prime your core

  • Tuck tailbone while simultaneously pulling belly button towards spine to feel low abdominal muscles tighten
  • Hold for 10 sec

3 X 10 reps

Glute strengthening - Activate your hips

  • Standing with feet hip width distance
  • Ben your knee slightly and hinge forward at your hips.
  • Kick back and our 45 deg, return to start position
  • The weight should be on the standing leg throughout the exercise
  • Activation will be felt on the side and back of your hip on both sides
  • **Can be done without the band as well

3 X 10 reps

When to Seek Further Investigation

Most running-related knee pain responds well to conservative care.

Seek further medical assessment if you notice:

  • Significant swelling
  • Locking or catching
  • Instability or giving way
  • Inability to bear weight
  • Sharp pain after a traumatic incident
  • Night pain that doesn’t ease

These signs may require imaging or specialist referral.

How We Treat Knee Pain at Therapy X

When someone comes to us with knee pain, we don’t just look at the knee.

We look at how you move, how you train, how you sit, and how you recover.

Because knee pain from running is rarely just about the knee.

At Therapy X in South Granville, Vancouver, your assessment is thorough. We examine your hips, ankles, core stability, posture, and running mechanics. We look at your training history, your footwear, your workload - the bigger picture. From there, your knee pain treatment is tailored specifically to you.

For some runners, that means focused physiotherapy to rebuild strength and control. For others, chiropractic care helps restore joint mobility and reduce mechanical stress. Sometimes soft tissue work with a registered massage therapist is what finally allows the right muscles to fire properly. In certain cases, acupuncture or shockwave therapy helps calm persistent irritation so your body can heal. And often? It’s a collaborative approach. That’s one of the biggest differences here.

We are a fully stacked multidisciplinary healthcare team. It’s common for clients to work with more than one clinician during their rehab. We collaborate closely, share clinical notes, and discuss cases when needed. You’re not bouncing between disconnected providers — you have a team aligned around one goal: getting you back to running strong.

If something falls outside our walls, we also have a trusted referral network across Vancouver. That includes experienced running retailers who assess gait and help match the right running shoes to your body and mechanics.

You’re supported from every angle.

Not sure where to start? Book an assessment with one of our expert physiotherapists and they will be able to guide you appropriately after a thorough assessment.

The Bigger Picture

Many runners quietly believe knee pain is just part of the sport - it’s not, it’s information. Your body is telling you something about strength, mechanics, load, or recovery. When you understand the “why,” you stop guessing. You stop chasing quick fixes. You start building resilience.

Our goal isn’t just short-term relief, it’s long-term capacity.

We pair hands-on treatment with personalized corrective exercises so you leave knowing what to work on — and why. You gain the tools to stay independent. And you’ll know exactly when and who to reach out to if symptoms start creeping back.

That’s how you run for the next 10, 20, 30 years.

Don’t wait until it sidelines you. If you’re dealing with knee pain while running — whether it’s on the outside of the knee, inside of the knee, worse downhill, or lingering after your runs — a proper assessment can change everything.

If you live or work near South Granville, Kitsilano, or Fairview, we’re right here in your neighbourhood. Book a comprehensive knee pain assessment at Therapy X in Vancouver.
